in this study cellular phosphatase activity, referred to as enzyme developed color (edc) assay, was used for an in vitro assessment of cell proliferation and cytotoxicity. optimum conditions were established and found to be 10 x103 cells / well at 37°c and 60 min incubation (for developing color). under the same conditions a direct correlation between optical density (00) and cell number was ob...

conclusions this is the first case report of a vanishing tumor in the right pulmonary apex. case presentation such masses have been designated as vanishing tumors of the lung. it is extremely rare that a vanishing tumor occurs in the apex of the lung. introduction in patients with acute heart failure, pleural fluid localized in an inter-pleural fissure produces a mass on chest x-ray, which mimi...

a discrete mibi avid lung lesion was found in cinematic views of myocardial perfusion imaging (mpi) of a 59 year-old woman. interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. mpi was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  she had no past...

background: inflammatory myofibroblastic tumor (imt) is a tumor composed of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. the most common sites of involvement include the lung, liver and orbit, but it has been reported to occur in nearly every site of the body, including oral cavity and soft tissue. although common in other sites, such a tumo...

Nine cases of carotid body tumor chemiodectomas in seven Patients are presented and diagnostic and therapeutic problems discussed Similar to other reports, many cases undergo operative exploration without correct preoper.ativ.e diagnosis or ability of the surgeon to handle such lesions. The most important factor for correct diagndsis is including carotid body in differential diagnosis of latera...

background: early detection is a key to survival for gastric cancer. molecular markers such as mirna (microrna) can have great importance in the early diagnosis of gastric cancer. expression of mir-21 and mir-221 are deregulated in many types of human cancers. this study aimed to investigate the differences in mirna expression patterns within the iranian population. methods: total rna was extra...
